论我国耐火材料用结合粘土的发展

DEVELOPMENT OF BOND CLAY USED FOR REF RACTORY MATERIAL in China

我国耐火材料用结合粘土由软质及半软质（古生代）耐火粘土原矿向（新生代）球粘土原矿及水洗或深加工的球粘土、高岭土及（古生代）耐火粘土发展．目前国内以广西南宁地区球粘土为最好的耐火材料用结合粘土。

The bond clay used for refractory material in China has been developed from raw soft and semisoft (paleozoic) refractory clay to raw ball clay (cenozoic) and washed or processed ball clay.kaolin and (Paleozoic) refractroy clay. So far the high grade ball clay from Nanning,Guangxi,is the best bond clay used for refractory material in China.
